Java Program to Handle Checked Exception
Checked exceptions are the subclass of the Exception class. These types of exceptions occur during the compile time of the program. These exceptions can be handled by the try-catch block otherwise the program will give a compilation error.
ClassNotFoundException, IOException, SQLException etc are the examples of the checked exceptions.
I/O Exception: This Program throw I/O exception because of due FileNotFoundException is a checked exception in Java. Anytime, we want to read a file from the file system, Java forces us to handle error situations where the file is not present in the given location.
Consider myfile.txt file does not exist.
This exception can be handled with the help of a try-catch block
- Declare the function using the throw keyword to avoid a Compilation error.
- All the exceptions throw object when they occur try statement allows you to define a block of code to be tested for errors and catch block captures the given exception object and perform required operations.
- Using a try-catch block defined output will be shown.
This Exception occurs when methods like Class.forName() and LoadClass Method etc unable to find the given class name as a parameter.
